Abstract (en)
[origin: WO2011104317A1] A hybrid laser (100) is described for generating radiation, the hybrid laser (100) comprising an optical passive material (110) and an optical active material (120). The hybrid laser (100) furthermore comprises a first optical waveguide (112) and optical laser components (114) comprising reflectors in the optical passive material (110). The first optical waveguide (112) is adapted for coupling out radiation from the hybrid laser. The laser also comprises a second optical waveguide (122) defined in the optical active material (120). The optical laser components (114) comprise reflectors defining a cavity and furthermore are adapted for providing laser cavity confinement in the first optical waveguide (112) and the second optical waveguide (122). The second optical waveguide (122) thereby is positioned at least partly over the first optical waveguide (112) so that an evanescent coupling interface is defined between the second optical waveguide (122) and the first optical waveguide (112) and the evanescent coupling interface is positioned within the laser cavity.
